Improved fruit-mill



EDMUND GREENLEE, @Il .RUNDIQLLA PENNSYLVANIA.

Letters Patent No. 86,391, dated February 2, 1869.

IMPROVED FRUIT-MILL.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it ma/y come/m:

Be it known that I, EDMUND Gnnmvnnn, of Rundells, in the county of Crawford, and State of Pennsylvania, have invented certain new and useful 11nprovements in Machinery for Grinding Fruits, and expressing the juice therefrom, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 represents a plan or top view of my improved machine.

Figure 2 represents a vertical longitudinal section through the same, at the line :c of ng. l.

Figure 3 represents a vertical transverse section through the same, at the line y y of fig. 1.

The object of my invention is eectively to reduce apples or other'fruit to pulp or pomace, vand to extract the juice therefrom; to which end,

The invention herein claimed consists in certain novel devices and combinations ot' mechanism hereinafter set i'orth.

The apples, or other fruit to be ground, are poured' into a hopper', A, and out up by spiked rollers, B C, revolving in the direction indicated by the arrows.

The smaller cylinder C revolves in a concave, C', arranged beneath it, and the larger one, B, revolves be-l tween two concaves, 113 b4, arranged, one on each side of it, as sho'wn in fig. 2.

The pomace escapes through the bottom of the. hopper and falls upon the centre of au endless or travelling-band, D, of cloth or other suitable material.

rl`his apron runs around four cigar-shaped flanged rollers, E, turning in suitable bearings in the frame A', and under a central tightening-roller, F, turning in boxes f iu vertically-slotted down-banging arms, F1, provided with tightening-wedges, F2, by which the tension of the belt may be regulated.

The peculiar form of the rollers aids in keeping the apron smooth-stretched.

After escaping from the hopper, the poinace is carried by the apron between several pairs of rollers, G H, Grl H, G2 H2, by which the juice is'expressed.

These rollers are of the peculiar form shown in the drawings.

The upper ones taper from each end toward the centre, so that a central longitudinal section thereof would be of a double-concave form, and are capable of being adj usted vertically by-set-screws la.. y

The lower rollers are of a cigar shape or double-con- Vex forni in longitudinal section, and provided at Veach end with flanges g, which overlap the ends of the upper rollers.

The rollers may be so adjusted as to give pressure to each pair greater than that of the preceding pair, and thus express the juice better.

The pomace travels on the centre ofthe rollers, and, owing to the peculiar shape of the under rollers, the

juice runs oli' sidewise, and is thus prevented from again being absorbed by the pomace, but is prevented .K,\whence it may be conveyed to any proper receptacle by suitable pipes or troughs.

The pomace, after passing through the rollers, is dropped, at the end oi' the machine, into any proper receptacle.

The driving-power is applied from any suitable prime mover, by means oi' a band encirclinga pulley, L, on

the driving-shaft L which carries the main cylinder B. l

A spur-pinion, l', on the opposite end of this shalt, drives a corresponding pinion on a short shaft be-.

neath it.

A bevel-wheel, l, on this shaft, drives a corresponding pinion, m, on a longitudinal shaft, M, supported in suitable bearings'outside of and parallelA with the frame,

and carrying worm-screws, 'n nl ai n?.

The forward worm n drives an idle-wheel, o, which drives a pinion, c", on the shaft c of the feedingor auxiliary cutting-cylinder G, while the others drive pinions O on the shafts g of their respective lower rolls.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination of the endless belt with the cigar-shaped rollers E and tightening-rollcr-F, arranged and operating as described.

2. The combination, substantially as described, of an endless belt, flanged cigar-shaped under wllers,.and adjustable concave pressure-rollers, for the purposes specified.

3. The combination, substantially cutting-cylinders and an endless belt, travelling beneath the cylinders,A with a series of flanged cigarshaped rollers and concave rollers, arranged in pairs, with the belt passing between them. 4. The combination, substantially' as set forth, of cutting-cylinders, an endless travelling-belt, curved pressure-rollers, and a'straw screen, arranged for joint operation as speciiied.

In testimony whereof, I have hereunto subscribed my name.
